I have a Win2k8 R2 server serving as RDS and RDS licensing server and everything is working fine. I added another Win2K8 R2 server with the RDS role enabled. But this server is unable to obtain the RDS CALs from the licensing server. The licensing diagnosis on the 2nd server is able to recognize the licensing server and didn't show any error. The only thing I can see is this error message in the event viewer.
The RD Licensing grace period has expired and the service has not registered with a license server with installed licenses. A RD Licensing server is required for continuous operation. A Remote Desktop Session Host server can operate without a license server for 120 days after initial start up.
I added the 2nd server to the terminal server computers local group in the license server but that didn't make any difference. Changing the discovery scope on the licensing server from this domain to forest didn't help either.
We have a 2003 AD and both RDS servers are member servers.
